Problems solved by technology

Its disadvantages are: it is not suitable for asymmetric arc-shaped variable-section box girders; the cross-connection of the main truss on the beam surface will interfere with the construction to a certain extent, and when the beam surface needs the assistance of a truck crane for construction, the hanging basket The main truss cross-connection on the beam face will affect the traffic

Embodiment 1

[0024] Such as figure 1 , 3 -6. A hanging basket construction device for an asymmetric arc-shaped variable-section thin-flap box girder, which includes a load-bearing platform, a cable system 13, a running system, a push-resistance system in place, an anchoring system, an operating platform, and embedded parts system, the combined structure of the main frame of the box girder and the truss constitutes the load-bearing platform of the hanging basket, the main frame of the box girder includes the main longitudinal beam 3, the two sides of the main longitudinal beam are provided with the secondary longitudinal beam 4 through the cross connection 8, and the secondary longitudinal beam on one side is connected There is a gull-wing load-bearing truss 5, which is used for the oblique web and wing plate of the box girder on the side of the standard section, and a horizontal load-bearing truss 6 connected to the secondary longitudinal beam on the other side, which is used for the const...

Embodiment 2

[0026] Such as Figure 2-6 , the structure is similar to that of Example 1. The positions of the two beam surface triangular outer main trusses on the side of the variable cross-section side box girder are set differently. 1 Only one of the two is arranged on the upper end of the adjustable height and laterally movable inclined web truss. And preferably, the outer main girders of the beam surface triangle are arranged independently of each other, and they are located at the flange plate to ensure the balance of the asymmetric arc-shaped variable-section thin-flange box girder. The triangular main truss inside the beam surface is used for anchoring the load-bearing platform of the hanging basket and guiding the walking of the hanging basket. Two main longitudinal beams are arranged at intervals, and a horizontal connection is arranged between the two main longitudinal beams. The connecting piece is Ф40 finish-rolled rebar.

Abstract

Disclosed is a hanging basket construction device for an asymmetric arc-shaped variable cross-section thin wing plate box girder. A hanging basket is composed of girder surface triangular main trusses, a bearing platform, a cable-stretching system, a traveling system, an in-position anti-push system, an anchoring system, an operation platform, a pre-buried part system and the like. The bearing platform of the hanging basket is formed by a combined structure of a box girder main frame and trusses, so that the rigidity of the hanging basket is effectively controlled, self-weight of the hanging basket is reduced, and the cost is reduced. An empty basket traveling task of the hanging basket is finished by means of traveling trolleys, traveling tracks, crab claw type sliding blocks, steel lifting belts, the girder surface inner-side triangular main trusses and a hauling mechanism. During usage, the crab claw type sliding blocks are reversely hooked on the girder surface inner-side triangular main trusses, the crab claw type sliding blocks are connected with a bearing platform girder by being connected with the steel lifting belts, the tail of the bearing platform is anchored to a girder bottom plate through traveling wheels, the hauling mechanism hauls sliding shoes to move forwards, therefore, the bearing platform is driven to move forwards, and the traveling mode is steady and reliable.

Description

technical field [0001] The device relates to the field of bridge box girder construction, in particular to a hanging basket construction device for an asymmetric arc-shaped variable-section thin wing plate box girder. Background technique [0002] The existing hanging baskets used in the construction of box girders of cable-stayed bridges are designed for left-right symmetrical box girder structures. For the existing domestic hanging baskets, the main trusses on the beam surface are connected by cross-connecting beams, and the hanging baskets The whole is generally left-right symmetrical structure. Its disadvantages are: it is not suitable for asymmetric arc-shaped variable-section box girders; the cross-connection of the main truss on the beam surface will interfere with the construction to a certain extent, and when the beam surface needs the assistance of a truck crane for construction, the hanging basket The main truss cross-links on the beam face will affect the traffi...
